With McClellan ill, Abraham Lincoln calls a White House meeting with Irvin McDowell, William Franklin, Salmon Chase, Edwin Stanton, and Thomas Scott. Lincoln told them "..if McClellan is not going to use the Army anytime soon, I would like to borrow it."

General John McClernand [US] defeats Brigadier General T. J. Churchill [CS] at Fort Hindman or Arkansas Post. Defending the outpost on the Arkansas River, 5,000 Confederates are surrounded by a force of 50,000 Union troops, and a U. S. Naval squadron under the command of Admiral David Porter. The Navy silenced the Confederate artillery and McClernand attacked, gaining the outer walls. The Confederates then surrendered.
